Abstract

Un sistema de tuberías incluye una primera y una segunda tubería que tienen un primer y un segundo extremo soldados entre sí que forman una soldadura circunferencial, y un recubrimiento contra la corrosion que recubre la soldadura circunferencial. Además, se proporciona una lámina flexible para cubrir la soldadura circunferencial. La lámina flexible comprende una primera capa estructural que se acopla mecánicamente al recubrimiento contra la corrosion, donde el recubrimiento contra la corrosion impregna una parte substancial de la primera capa estructural. La lámina flexible también incluye una segunda capa que comprende una capa de polímero adherida a la primera capa, la segunda capa protege al recubrimiento contra la corrosion de posibles danos mecánicos o ambientales. Alternativamente, la cubierta protectora comprende un material polimérico e incluye un orificio formado a través de ella adaptado para recibir un mecanismo de suministro que suministra un recubrimiento contra la corrosion a la soldadura circunferencial.A pipe system includes a first and a second pipe that have a first and a second end welded together that form a circumferential weld, and a corrosion coating that covers the circumferential weld. In addition, a flexible sheet is provided to cover the circumferential weld. The flexible sheet comprises a first structural layer that is mechanically coupled to the corrosion coating, where the corrosion coating permeates a substantial part of the first structural layer. The flexible sheet also includes a second layer comprising a polymer layer adhered to the first layer, the second layer protects the coating against corrosion from possible mechanical or environmental damage. Alternatively, the protective cover comprises a polymeric material and includes a hole formed therethrough adapted to receive a delivery mechanism that supplies a coating against corrosion to the circumferential weld.
